Abstract (en)

[origin: WO2017021651A1] The invention relates to a method and device for controlling the pressure (PGC) and a mixture ratio of a rocket engine on the basis of a set pressure value (PGCc) and set mixture ratio value (RMc). In said method and device, a control generates signals for controlling two control valves (VR1, VR2) of said engine, the control using a pressure feedback loop. Said control also uses a determination of an estimated mixture ratio value (RMe). The estimated mixture ratio value is obtained by a model generating estimated mixture ratio values from at least one of the two signals for controlling control valves and/or the measured pressure.
